Research On Key Techniques Of The Generalization For UAV Tt&c System

With the widely application of the unmanned aerial vehicle(UAV) in various fields, including aunit or group may have a variety of types, complex function and a wide range of unmanned aerialvehicle is the current approach for each type of UAV is equipped with a set of specific UAVmeasurement and control system, in the UAV development, production, maintenance and use ofunnecessary redundant construction and waste. This paper emphatically study the unification of theunmanned aerial vehicle control system, main selected to study the key technology as follows:1) this paper expounds the measurement and control system and flight control computer interfacebetween the benefits of unified frame structure, the frame structure of scientific planning, dynamicconfiguration of frame structure, make its have generalized function; Frame structure was designedcalibration method, with functions of inspection and error correction;2) Generalized solution is proposed in this paper the airborne terminal, and illustrates theadvantages compared with traditional way of generalization, choose three initial feasible designscheme, realize the user can select custom implementation;3) the research chose appropriate modulation system unified solution, discussed the basis ofOFDM modulation demodulation system, it compares the advantages and disadvantages of OFDMsystem and the traditional system, and the peak than reduce technology were studied, finally OFDMsystem is verified by the simulation on the multipath effect and narrow band interference ability andadvantage;4) study and formulate the unified interface display, shows that compared with the traditionalway, the benefits of general requirements put forward the software design, parameter display and mapand track display requirements, external interface requirements, design the specific control, missioncontrol for flight control, link and integration situation display of3d software design in detail.Based on the concept of generalized unmanned aerial vehicle (uav) tt&c system is put forward,formed a relatively general theory of unmanned aerial vehicle (uav) tt&c system key technology, todevelop a reliable and flexible way of generalization, in order to achieve good effect in practice withthe purpose of promoting value, at the same time sprang out effect.
